Java Concurrent Program issue

Question

Hello,
I am fairly new the Java Concurrent Programs concept. I was just trying a simple Hello World example but I cannot seem to run it from the operating system. Here is my Hello World java program I created using Jdeveloper:
package oracle.apps.fnd.cp.request;
public class Hello implements JavaConcurrentProgram {
public static final String RCS_ID = "$Header$";
public void runProgram(CpContext ctx) {
ctx.getLogFile().writeln("-- Hello World! --", 0);
ctx.getOutFile().writeln("-- Hello World! --");
ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
It compiles fine in Jdev generating the class file. Here is what I did :
1) Created directory under $JAVA_TOP as follows :
mkdir $JAVA_TOP/oracle/apps/fnd/cp/sample
2) moved the Hello.java file there under sample directory
3) compiled java file using avac $JAVA_TOP/oracle/apps/fnd/cp/sample/Hello.java ( It compiles fine generating the class file )
4) Now I wanted to test running it : I tried using jre command first as I saw in other posts but this is not working :
jre -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
Error :
ksh: jre: not found
Then I tried using the other way I saw on posts which is using the java command :
java -cp $AF_CLASSPATH -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
This gives me the following error :
java.lang.NoClassDefFoundError: oracle/apps/fnd/cp/sample/Hello (wrong name: oracle/apps/fnd/cp/request/Hello)

at oracle.apps.fnd.cp.request.Run.main(Run.java:157)
Can anyone tell me what I am doing wrong ? I have tried everything even tried ftp the class file from my local but I get the same error. Any help would be appreciated.
Thanks

Ajay,
Yes you are right. I did not register my java program yet in the concurrent programs.
I thought I could test it out from the operating system command line before registering it. But looking at your document you sent me it seems I have to do all the steps i.e. define concurrent program etc before I can test it from the operating system. If that's the case then what's the use of trying to test it via operating system using
java -cp $AF_CLASSPATH -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
Thanks
